PHPMailer < 5.2.20 Remote Code Execution PoC 0day Exploit
(CVE-2016-10045) (Bypass of the CVE-2016-1033 patch)

Discovered by Dawid Golunski (@dawid_golunski)

Desc:

I discovered that the current PHPMailer versions (< 5.2.20) were still
vulnerable to RCE as it is possible to bypass the currently available
patch.

This was reported responsibly to the vendor & assigned a CVEID on the
26th of December.
The vendor has been working on a new patch which would fix the problem but
not break the RFC too badly. The patch should be published very soon.

I'm releasing this as a 0day without the new patch available publicly
as a potential bypass was publicly discussed on oss-sec list with Solar
Designer in the PHPMailer < 5.2.18 thread, so holding the advisory
further would serve no purpose.
